| 摘 要： | 将空间巨型框架结构的辅助框架中的柱只考虑其轴向变形,将其沿巨型框架梁的轴线方向连续化后,作为巨型梁单元的弹性地基,然后将巨型柱和巨型弹性地基梁组成空间巨型框架,在考虑了地基的弹性变形后,用矩阵位移法对其进行静力分析。计算结果表明:分析方法是合理、有效的。

| Abstract: | The paper deals with static analysis of a mega space frame. The axial rigidity of columns of subsidiary frames of the mega space frame is simplified as elastic subgrade along the axes of the mega beams. The mega space frame is then composed of the mega columns and the mega beams on elastic subgrade. Static analysis of the mega frame is performed with matrix displacement method considering deformation of the soil. The results indicate that the analytical method is rational and effective. |

| Keywords: | mega space frame elastic subgrade matrix displacement method equivalent rigidity of elastic subgrade static analysis |
